“…A recent report, which assessed taste using a 35-question survey (sample question: Have you experienced an increase in taste for sweet foods? ), revealed that the majority of individuals that have received VSG and RYGB, report alterations in taste, with significant increases in the taste for sweets, salty foods and sour foods [133].…”

“…Long term decreases in dietary fat intake and avoidance of fatty foods have been reported following [84,128]. The majority of RYGB patients report subjective changes in taste and an aversion to specific foods, with the most commonly avoided food items being meat products [87,133]. Additionally, food cravings for sweets and fast food were lower following surgery and the level of pleasure reported following sucrose administration decreased over time in the RYGB group [72].…”

There is a large body of evidence indicating that bariatric surgery provides durable weight loss and health benefits to patients who are obese and have comorbidities such as type 2 diabetes (T2D). However, there are still many questions related to mechanisms of metabolic improvement, predictors of success/failure, and long term consequences, which need to be answered. More recently, there has been a particular interest in the modulation of taste and food preferences that occurs after bariatric surgery and how this affects weight loss in different individuals. Animal models as well as human studies have shed some light on the role of taste in changing food preferences and how these changes may affect weight loss after surgery. The goal of this review is to discuss the physiological and behavioral consequences of bariatric surgery as a treatment for obesity and T2D, with particular emphasis on recent studies describing bariatric surgery-induced modifications in taste perception and food preferences.

“…Additionally, they reported that patients who developed food aversions achieved higher absolute post-operative weight loss and greater reduction in body mass index (BMI) (Graham et al, 2014). Zerrweck et al using the questionnaire from Graham et al, reported that appetite, taste, smell and food aversions were equally common following RYGB and SG at 10 months post-surgery (Zerrweck et al, 2015). However, it remains unclear whether these subjective changes in appetite, taste and smell are a consequence of weight loss per se or if they are mediated by bariatric procedure-dependent physiological changes.…”

Reported appetite, taste and smell changes following Roux-en-Y gastric bypass and sleeve gastrectomy: Effect of gender, type 2 diabetes and relationship to post-operative weight loss

et al. 2016

Reduced energy intake drives weight loss following Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) procedures. Post-operative changes in subjective appetite, taste, and smell and food preferences are reported and suggested to contribute to reduced energy intake. We aimed to investigate the prevalence of these changes following RYGB and SG and to evaluate their relationship with weight loss. 98 patients post-RYGB and 155 post-SG from a single bariatric centre were recruited to a cross-sectional study. Participants completed a questionnaire, previously utilised in post-operative bariatric patients, to assess the prevalence of post-operative food aversions and subjective changes in appetite, taste and smell. Anthropometric data were collected and percentage weight loss (%WL) was calculated. The relationship between food aversions, changes in appetite, taste and smell and %WL was assessed. The influence of time post-surgery, gender and type 2 diabetes (T2D) were evaluated. Following RYGB and SG the majority of patients reported food aversions (RYGB = 62%, SG = 59%), appetite changes (RYGB = 91%, SG = 91%) and taste changes (RYGB = 64%, SG = 59%). Smell changes were more common post-RYGB than post-SG (RYGB = 41%, SG = 28%, p = 0.039). No temporal effect was observed post-RYGB. In contrast, the prevalence of appetite changes decreased significantly with time following SG. Post-operative appetite changes associated with and predicted higher %WL post-SG but not post-RYGB. Taste changes associated with and predicted higher %WL following RYGB but not post-SG. There was no gender effect post-RYGB. Post-SG taste changes were less common in males (female = 65%, males = 40%, p = 0.008). T2D status in females did not influence post-operative subjective changes. However, in males with T2D, taste changes were less common post-SG than post-RYGB together with lower %WL (RYGB = 27.5 ± 2.7, SG = 14.6 ± 2.1, p = 0.003). Further research is warranted to define the biology underlying these differences and to individualise treatments.

“…An interesting possibility is that the reduced appetite or shift in macronutrient preference seen with bariatric surgery is not because some foods are found to be more favorable than others but, instead, because ingestion of certain foods leads to aversive side‐effects. Many patients report feelings of food‐induced sickness after either RYGB or VSG . Indeed, greater weight loss is correlated with reports of greater food‐induced aversion .…”

To date, bariatric surgery remains the most effective strategy for the treatment of obesity and its comorbidities. However, given the enormity of the obesity epidemic, and sometimes variable results, it is not a feasible strategy for the treatment of all obese patients. A simple PubMed search for ‘bariatric surgery' reveals over 28 000 papers that have been published since the 1940s when the first bariatric surgeries were performed. However, there is still an incomplete understanding of the mechanisms for the weight loss and metabolic success of surgery. An understanding of the mechanisms is important because it may lead to greater understanding of the pathophysiology of obesity and thus surgery‐alternative strategies for the treatment of all obese patients. In this review, the potential mechanisms that underlie the success of surgery are discussed, with a focus on the potential endocrine, neural and other circulatory factors (eg, bile acids) that have been proposed to play a role.

Taste and Olfactory Changes Following Laparoscopic Gastric Bypass and Sleeve Gastrectomy

Abstract: The majority of patients presented taste and olfactory changes soon after surgery independently of type of procedure. Patients submitted to LGBP referred more often a different smell in food. Higher %EWL was observed in patients presenting any food aversion, especially in the LGBP group.
